GAS METER.

Substitute for application serial No. 688,141,:fi1ed January 24, 1924. This application filed December 4,

' 1925. Serial No. 73,263.

The present invention is directed to improvements in gas meters and particularly to wet-gas meters.

Anobject of the invention istoprovlde a meter so constructed that the drum thereof can be removed from the casing to permit repair or adjustmentof the parts in an easy an d convenient manner.

The crownsot meters of this type heretofore have been bolted. to the interior of the casing and are associated in such Way with the druinthat-it is necessary to remove the crowns to permit the removal of the drum and this invention has been perfected to overcome this disadvantageous condition.

vide a casing soconstruct'ed that the incomling gas which as well known is of substantially the same temperature the year around will retainthe sealing oil. in substantially the same fluidity, thereby permitting the device tooperate in an even manner. ,1

With these and other objccts'in view ,as

will appear as the description proceeds, the

invention consists inthe novel features of construction combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out 121 the appended claims.

In the accompanying drawing:

Figure 1 is a vertical sectional view through the device,

Figure 2 is a sectional View on line 22 of Figure 1, y

Figure 3 is a sectional view on line 33 of Figure 1, and

Figure 4 is a vertical. sectional view showing a modified form of the invention.

Referring to the drawings 1 designates the casing, the lower portion 2 of which circular in cross-section and the upper portion 3 is oval in cross section so that said casing will produce a net appearance.

Located in the casing; 1 is a sealing oil container i, the wall of which is spaced from the wall of the lower portion 2 of the easing 1 by the Web 3 to produce an annular gas receiving chamber 5. The bottom Golf the container 4 is spaced above the bottom of the casing 1 and is concavo-convex in crosssection so as to produce a comparatively large compartment 7 for the reception of grit or any Foreign matter which in ay enter the casing 1 with the gas, this foreign matter will by is a universal. coupling 10 which in turn obviously collect in the compartment 7 and will not, enter the valve structure. 1

Upon the convex or upper surface of the bottom 6 is aplurality of circularly aligned connectedto the fluid idistributinr valve connect ng 1nechanism 1 and since this mechanismis well. lmown Rilfititll description thercotis not thought necessary. As cus- A further object of the invention is to proternary this valvemechanism supports the usual casing 12 which surrounds thb tube 9.

The drum 13 includes a plurality of meat urlng pockets 14corresponding in number to the crowns 8 andhs usual. these pockets successively conin'iunicate with the "tube 9 7 through the valve ports 15 in a well known manner to permit the gas to flow in measured quantiticsto its pointof use.

Heretofqre the crowns 8 have. been bolted within the casing and are of such dimensions that it was necessary that they be released or unbolted before the drum could be removed from the casing.

To overcome this annoyance I have permanently secured the crowns 8 to the bottom 6 of the container 4; and it will be ol'iserve'd that the diameter of the openings 16 of the drum is greater than the coinliiincd transverse diameter of the upper ends of the crowns thereby permitting; said drum to be freely llli'tOCl from the container Without affectingor disturbing said crowns.

The gas supply pipe 17 communicates through the port 17 n the web 3 with the annular gas chamber 5, the incoming gas thereby encircles the container 4. and retains the sealing oil at substantially an even tempcraturo regardless of climatic changes. The gas after passing through the tube 9 enters the valve ,incchanism 11 and from thence passes to the outlet pipe 18 to its point of use.

Secured below the top 19 to the casing is a hanger 20 provided axially with a journal 20 and journaled therein is'a Worm 21, rotary inoven'ient being imparted to the worm through the medium of the link 22 connected with the valve actuating rod 23. Supported upon the hanger is a bracket 24 and journaled therein isa shaft 25 to which is fixed the worm wheel 26 adapted to mesh with the worm 21 to impart rotary movement to said shaft which in turn actuates any well known form of registering mechanism.

' ter will readily To vary the inclination of the drum 13,.

the journal 20 is threaded in the hanger 20 and vis raised or lowered by turning the knurled Wheel 30. It will readily be seen that'this action. variesthe horizontal distance/between the ends of the link 22 and correspondingly changes the axial inclination of the drum 13. When the proper adjustment' is made it is'locked by the nut 31.

In Figure 4, the modified form of the invention, the sealing oil container 27 is formed from glass, the conducting tube 28 and crowns 29 being molded integral with said container.

It will be obvious that any foreign particles which may enter the annular chamber 5 with theincoming gas will settle upon the bottom'of the casing 1 and in the compartment 7. This foreignmatter may be readily removed upon removing. the drum 13 and inverting the casing'l and since the bottom 6 of the container is concave the foreign matenter the tube 9 when the casa gas circulating chamber between the walls of the casing and the walls of said container, a gas inlet communicating with said chamber and a gas outlet formed with said casing and arran ed in communication with the interior of said container.

2. A gas meter comprising a casing, an inwardly directed flange at the upper end of said casing, a sealing liquid container extending into the casing and spaced from the latter by means of said flange to provide a gas circulating chamber between the walls of the casing and the walls of said container, a as inlet entering said chamber, and a gas outlet having communication with said container.

3. A gas meter comprising a casing, a seal ing liquid container extending into the res ing, a lateral extending flange between the casing and the container and arranged to confine the container within said casing in a spaced relationship therefrom to provide a gas circulating chamber around said li uid container, a gas inlet entering said cham r, and a gas outlet having communication with said container.

4. A meter of the class described comprising a casing, a sealing oil container located in the casing and having a lurality of crowns carried thereby, a drum aving a plurality of measuring pockets for cooperation with the crowns, the open end of said 'drum being greater in diameter than the combined diameter of the crowns to permit said drum to be freely disenga ed from said crowns.

In testimony w ereof I aflix my signature.
